   Where was thiochrome obtained?

   • Thiochrome was procured from Sigma Aldrich. Oxodihydrothiochrome and its oxidation product (OP1) were prepared by the oxidation of thiochrome and oxodihydrothiochrome, respectively, according to the previously described methods [ 8, 28 ]. All the reagents and solvents were of analytical grade obtained from Merck.

   Which adduct of thiamine undergoes simultaneous cleavage?

   • In [A], the H 3 C–O 2 ˙ adduct of thiamine undergoes simultaneous cleavage of the C–H and O–O bonds, leading to a very stable 2 (3 H )-thiazolone intermediate. The same intermediate was obtained after the cleavage of the C–H and O–H bonds of the HO adduct of thiamine in [B] and [C].

   How does UV light affect photolysis of thiochrome (THC)?

   • Photolysis of thiochrome (THC) by UV light has been studied in the pH range 7.0–12.0. THC is photooxidized to oxodihydrothiochrome (ODTHC) in alkaline solution. Photolysis of THC follows consecutive first-order kinetics to form oxidation products. THC photolysis is pH dependent and is enhanced with pH in alkaline solution.
